To protect a computer completely from electrical problems you would have to keep it unplugged. Unfortunately this makes it useless.
Using surge protection on the power supply is a simple and relatively cheap protection from spikes in the power supply. A UPS or uninteruptible power supply can be set up to allow the computer to run for a period of time after a breakdown in the power supply. These are more expensive the longer they can supply power, and are often set up to supply power for just long enough to do a save and tidy shutdown of the computer.
People who use the computer are often simply known as "users".
Users can communicate to their computer using the keyboard. Another device that can be used to communicate to a computer is the mouse.

Most computer users use PCs, (personal computers). These general purpose computers can be used for pretty much anything, chances are that you are viewing this webpage on a PC right now. Smart Phones can also be considered computers, since they perform computational tasks and have almost all the elements of a regular computer.
Users of computers want to do things with their computers. Applications are programs that allow people to actually do things with a computer. Almost every program a users uses is an application. Systems software is what makes the computer work. They are needed to make applications work. Users don't really use the system software directly, but rather the applications on their computers. Some applications come with computers, so can be got for free and some need to be purchased. So some users will buy applications for that reason.Users of computers want to do things with their computers. Applications are programs that allow people to actually do things with a computer.

MAINFRAME COMPUTERMINI-COMPUTERMICRO-COMPUTERSUPER-COMPUTERThere are many computers which are different from each other in various aspects. Classification of computers are given below.(1) Micro computers: These computers use a microprocessor chip and this chip is used instead of CPU means that this microprocessor chip works as a CPU.These computers are also called personal computers. Two major types of these computers are laptop or Desktop computers. Only one user uses these computers at time that's why they are also known as personal computers.(2) Mini Computers: These are powerful computer. These computers come into existence in 1960s at that time mainframe computer was very costly. Mini computers were available in cheap prices, so users start using it.(3) Mainframe Computer: It as a very powerful and large computer. You can get idea of its power as it can handle processing of many users at a time.Terminals are used to connect a user to this computer and users submit there task through mainframe. Terminal is a device which has keyboard and a screen. By using terminal users put inputs into the computer and get the output through screen.(4) Super Computers: As the name "super computer" specifies that these are most powerful computers even than mainframe. Actually, when we optimize a mainframe computer then we get super computer.(5) Microprocessor: You will find these computers everywhere. Microprocessor chips are used in many devices as I-pod, DVD, headphone etc.
Computer users who are not computer professionals are often referred to as "end users" or "casual users." They typically use computers for basic tasks like browsing the internet, using office applications, or consuming media, without having specialized technical skills. In some contexts, they may also be called "lay users" or "non-technical users."
The internet, sometimes called simply "the Net," is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).
